CONTINUOUS MACHINE FOR TREATING FABRICS.

Application :tiled September 16, 1927. Serial No. 220,033.

This invention relates to a washing or scouring machine for cloth in thecut and is also applicable to bleaching and dyemg machines for treatingfabrics continuously 1n 5 long lengths. i

The principal object of the inventlon 1s to provide an arrangement inthe case of washing or scouring machines by whlch the cloth, as it comesfrom a crabbing machine l with several cuts of cloth in a single length,

can be taken therefrom and threaded into the scouring machine, withoutripping apart saving in the process of dyeing and bleaching. Theinvention also involves the provision of means located back of the rollsfor guiding the clothalong the machine from one' end to the other inorder to provide for the continuous operation and other features ofconstruction and combinations of parts.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanyindrawings in which e ig. 1 is afront view of a scouring machine with a preferred embodiment of thisinvention applied thereto;

Fig. 2 is a sectional view of the same on' the line 2-2 of Fig. 1;

o Fig. 3 is .an end view of the ladder and associated parts extendingalong the back of the machine; and' Fig. 4 is a view like Fig. 2 on asmall scale showing the invention as applied to a reel machine fordyeing or bleac ing.

Ordinarily, cloth comes from the loom in cuts which are about fiftyyards long and ordinarily is taken through a fulling or crabbingmachine. The cloth goes through the fulllng machine in fifty yardlengths and together. In the ordinary machine' it is' stopped eighttimes. After Washing, the cloth goes to the vacuum extractor, before itenters which, it is sewedtogether to form a single length of eight ofthese cuts.

When a crabbing machine is used, the eight cuts of cloth are sewedtogether .in one long length While it is going through the machine. Whenit comes out, these seams are ripped apart to put it through theordinary scouring machine and then they are sewed together again to gothrough the extractor and folding machine in one length.

This machine is designedto save all but two -of the ripping and sewingoperations and, not merely to save these operations but, to save thedelay occasioned by their taking place while the machine is stoppedoncev for each seam. In this machine, the `cloth coming in one longlength from the crabbing machine does not have to beripped into eightlengths and then sewed eight times, but is simply ripped once and thenstrung intothis present machine and sewed once 80 to make an endlessstrand. On coming out, it is simply ripped once kand put into theextractor, through which` it goes in one long length to the foldingmachine.

I have shown the invention as applied `to well known types of scouringand dyeing machines. Referring to Figs. 1 and 2, the cloth comesthrougha series of eyes 10.

" Instead of each length passing through a separate eye, the wholelength of'eght pieces 90 is strung through the several eyes 10 one afterthe other in the manner indicated.

process is repeated over `and over..`

Asesl At the end the fabric goes up from the bottom past the last eyeover a guide-roll 16 mounted on the shaft with the roll 11 under a roll17 which is hung on a lever 18 and weighted Iwith a weight 19 so as tosqueeze some of the liquor out, then up over a guide-roll 20 which ismounted on another ladder or convenient support 21. The cloth -vis drawnthrough here to another guide-roll 22 through a wicket or loop 23 toguide the cloth so that it will necessarily pass-over -this roll 22 andnot run 0H the ends thereof and then goes down under a guide-roll 24and. either out of the machine or back to the base through the liquorseveral more times. The three guide-rolls 20,

`'22 and'24 are ofthe same size preferably.

The upper ladder merely supports the cloth in case there is any slackbetween the rolls 20 and 23. It will be noticed that the fabric comes upto the eyes at an inclination instead of vertically as heretofore andthat has an advantage inthat the cloth is prevented from being rumpledup just before 1t enters the eye but, on account of the inclination, isallowed to spread by gravity. The roll 16 is made larger than the roll11 to take up the slack and feed it forwardl more rapidly.

lhe showing of the invention in Fig. 4 as. applied' to a bleaching ordyeing machme is to illustrate another way in which the invention can becarried out, in which a reel 30 is employed over which the clothv glosstime after time in a progressive manner omI one end to the other as itgoes through the machine. Here the liquor drains out between the'operations. The
